I do not know what H & C stands for...their website does not say. It really does not matter, as they are known simply as H&C. They are a well known company specializing in all types of concrete products and are sold at Home Depot, Lowes and Sherwin Williams as well as other places.

As villagetinker wisely said, you mix the shark grip in with the clear coat/sealer.
I have used this on the clear coat over the epoxy finish in my garage and also over the stain finish on both my patio and driveway. I have stained both my driveway and my patio and my lanai/screenroom, then applied a clear finish with the shark grip.

I personally like staining the concrete, as it hides discoloration and staining, then the sealer protects the concrete from further staining from fertilizer, sprinkler water, downspout drainage, acid stains from electric golfcarts, etc.

Hope this helps...
